The U.S. Geological Survey measured the quake at 6.0, while the Philippine Institute of Volcanology and Seismology (Phivolcs) put it at 6.1.
It struck in the South China Sea off the west coast of Mindoro island at 2:23 p.m. local (0623 GMT).
Local seismologist Ismael Narag said the quake generated enough potential power to unleash big waves, but added that the authorities did not think it was capable of triggering a tsunami so Phivolcs issued no warning.
"It would have to be at least 6.5 magnitude to generate a tsunami," he said over local radio.
The earth's disturbance occurred about 50.1 kilometers (31.1 miles) beneath the surface, according to a U.S. Geological Survey advisory.
It gave the center at a spot about 30 kilometers off Calintaan, a western Mindoro town of 24,000 people.
(0623 GMT).
